Thank you for the reply. Actually, I believe I described the desired command output poorly. In the snippet I posted, the 'exports' array would define the resources that I'd want to define:

Code:
declare -A exports
exports[${nfsenv}-${dirs[0]}-10.1]=${cs101}
exports[${nfsenv}-${dirs[1]}-10.91]=${cs1091}
exports[${nfsenv}-${dirs[2]}-10.1]=${cs101}
exports[${nfsenv}-${dirs[2]}-10.91]=${cs1091}

So the commands I'd want to run would be:

Code:
pcs resource create nfs-b2b-hg-media-10.1 exportfs clientspec=10.1.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/media fsid=1 --group nfsgroup
pcs resource create nfs-b2b-hg-hotdrive-10.91 exportfs clientspec=10.91.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/hotdrive fsid=2 --group nfsgroup
pcs resource create nfs-b2b-hg-images-10.1 exportfs clientspec=10.1.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/images fsid=3 --group nfsgroup
pcs resource create nfs-b2b-hg-images-10.91 exportfs clientspec=10.91.0.0/255.255.0.0 options=rw,sync,no_root_squash directory=/nfs/exports/images fsid=3 --group nfsgroup

Notice the need to increment the 'fsid' based upon the exported directory (media=1, hotdrive=2, images=3). If a given directory is exported to multiple subnets, it will maintain the same 'fsid'.

I will test further and welcome any suggestions.

Thanks,

HB
